A unified smoking automated colorimetric system for the analysis of the gas phase of cigarette smoke and its application to the determination of hydrogen sulfideA system has been developed wherein the gas phase produced by smoking cigarette through a Cambridge pad is analyzed, on a puff-by-puff basis, for a desired component using automated colorimetry. The system consists of an AutoAnalyzer I and a simple, 1 ...

The use of pressure drop measurements for estimating ventilation and paper porosityEquations were derived for calculating dilutions in vented cigarette filters and tobacco columns from pressure drop measurements. These calculated dilutions are found to agree closely with those directly measured for a variety of commercial and ...
